Description
Die Erfindung betrifft eine Axialkolbenmaschine mit einer Schrägscheibe und einem mit Drehmomentübertragungsmitteln versehenen Zylinderblock, der mittels einer radial zwischen dem Zylinderblock und einem Gehäuse angeordneten Lageranordnung dreh bar gelagert ist.The invention relates to an axial piston machine with a swash plate and a Torque transmission means provided cylinder block by means of a radial rotated between the cylinder block and a housing arranged bearing assembly is stored in bar.
Eine derartige Axialkolbenmaschine ist aus der DE 198 54 415 A1 bekannt. Sie besitzt im Gegensatz zu den herkömmlichen Axialkolbenmaschinen in Schrägscheibenbau weise keine Triebwelle, auf der der Zylinderblock gelagert ist. Der Zylinderblock weist vielmehr eine sogenannte "Außenlagerung" auf. Die Zu- und Abfuhr von Druckmittel zu und von den Zylinderbohrungen, die in den Zylinderblock eingearbeitet sind, erfolgt durch Kanäle in der Schrägscheibe, den Gleitschuhen und den Arbeitskolben. Die Steuerfläche ist also auf der Schrägscheibe angeordnet. Wegen des relativ großen Durchmessers der Steuerfläche ist eine hohe Fertigungsgenauigkeit und ein dem entsprechend großer Fertigungsaufwand erforderlich, um Leckverluste klein zu halten.Such an axial piston machine is known from DE 198 54 415 A1. she owns in contrast to the conventional axial piston machines in swash plate construction as no drive shaft on which the cylinder block is mounted. The cylinder block points rather a so-called "external storage". The supply and discharge of pressure medium and from the cylinder bores that are machined into the cylinder block through channels in the swash plate, the sliding shoes and the working piston. The Control surface is thus arranged on the swash plate. Because of the relatively large Diameter of the control surface is high manufacturing accuracy and that a correspondingly large manufacturing effort is required in order to keep leak losses small.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Axialkolbenmaschine der eingangs genannten Art zur Verfügung zu stellen, die kompakte Abmessungen und eine verbesserte Druckmittelversorgung aufweist.The object of the present invention is an axial piston machine of the type mentioned to provide the compact dimensions and has an improved pressure medium supply.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Zylinderblock und die Schrägscheibe von zwei zueinander koaxialen Steckrohren zentrisch durchsetzt sind, die an den schrägscheibenseitigen Enden an Druckmittel-Versorgungskanäle ange schlossen sind und an den zylinderblockseitigen Enden in einem Steuerkörper mün den, der eine mit dem Zylinderblock zusammenwirkende Steuerfläche aufweist.This object is achieved in that the cylinder block and the Swashplate are centrally penetrated by two coaxial plug-in tubes, attached to the pressure medium supply channels at the swashplate ends are closed and mün at the cylinder block ends in a control body the one that has a control surface interacting with the cylinder block.
Der erfindungswesentliche Gedanke besteht demnach darin, den innerhalb der Axial kolbenmaschine durch den Entfall der Triebwelle zur Verfügung stehenden Platz zur Versorgung der Zylinderbohrungen mit Druckmittel zu nutzen. Dadurch kann im Bereich des Zylinderblocks eine Steuerfläche zur Verfügung gestellt werden, die in fertigungstechnisch vorteilhafter Weise einen kleinen Durchmesser aufweist und geringste Leckölverluste ermöglicht. The idea essential to the invention is therefore that within the axial piston machine due to the elimination of the drive shaft Use the supply of cylinder bores with pressure medium. This allows in A control surface can be made available in the area of the cylinder block has a small diameter in terms of production technology and lowest leakage oil losses possible.
Zur Minimierung der Abmessungen der erfindungsgemäßen Axialkolbenmaschine wird vorgeschlagen, dass der Steuerkörper innerhalb des Zylinderblocks angeordnet ist.To minimize the dimensions of the axial piston machine according to the invention proposed that the control body is arranged within the cylinder block.
Zweckmäßigerweise sind die Steckrohre in einer Schrägscheibenaufnahme und im Zylinderblock abgestützt.The plug-in tubes are expediently in a swashplate receptacle and Cylinder block supported.
Sofern radial zwischen dem Zylinderblock und dem Gehäuse eine Bremse, insbeson dere eine Federspeicher-Lamellenbremse, angeordnet ist, kann der rotierende Zylinderblock stillgesetzt werden.If there is a brake radially between the cylinder block and the housing, in particular which is a spring-loaded multi-disc brake, the rotating Cylinder block are stopped.
Hierbei ist es aus Platzgründen günstig, wenn sich die Bremse axial zwischen zwei Schrägwälzlagern der Lageranordnung, insbesondere zwei Kegelrollenlagern in O-Anordnung, befindet.For reasons of space, it is advantageous if the brake is axially between two Angular contact bearings of the bearing arrangement, in particular two tapered roller bearings in O arrangement.
Besonders vorteilhaft ist eine Ausgestaltung der Erfindung, bei der die Lageranordnung zur Aufnahme von Triebwerkskräften und von äußeren Käften ausgebildet ist. Es bedarf daher keiner gesonderten Lager, um äußere Kräfte, z. B. Radkräfte, aufnehmen zu können.An embodiment of the invention in which the bearing arrangement is particularly advantageous is designed to absorb engine forces and external forces. It therefore does not need a separate bearing to external forces, for. B. record wheel forces to be able to.
Die erfindungsgemäße Axialkolbenmaschine kann dadurch mit Vorteil als Radmotor ausgebildet werden. Es handelt sich dabei um einen Radmotor mit Direktantrieb, d. h. um einen Radantrieb ohne Untersetzungsgetriebe.The axial piston machine according to the invention can thereby advantageously as a wheel motor be formed. It is a direct drive wheel motor, i.e. H. around a wheel drive without a reduction gear.
Für den genannten Anwendungsfall ist es günstig, wenn an dem Zylinderblock ein Felgen-Mitnahmeflansch angeformt ist. Die Zahl der zu montierenden Bauteile wird dadurch gering gehalten.For the application mentioned, it is advantageous if a on the cylinder block Rim driving flange is formed. The number of components to be assembled is thereby kept low.
Der gleiche Vorteil ergibt sich durch eine Ausgestaltung, gemäß der an dem Zylinder block eine Felgenzentrierung angeformt ist.The same advantage results from a configuration according to which on the cylinder block a rim centering is formed.
Weitere Vorteile und Einzelheiten der Erfindung werden anhand des in der Figur schematisch dargestellten Ausführungsbeispieles näher erläutert.

An dem Zylinder block 2 sind eine Felgenzentrierung 2a und ein Felgen-Mitnahmeflansch 2b (Dreh momentmitnahme) angeformt.Radially between the cylinder block 2 and the housing 1 and axially between the two angular contact bearings 3 and 4 of the bearing arrangement there is a brake 11 designed as a wet spring-loaded disk brake. On the cylinder block 2 , a rim centering 2 a and a rim driving flange 2 b (torque driving) are formed.
Sowohl der Zylinderblock 2 als auch die Schrägscheibe 8 sind zentrisch von zwei zu einander koaxialen Steckrohren 12 und 13 durchsetzt, die im Zylinderblock 2 und schrägscheibenseitig in der Schrägscheibenaufnahme 9 abgestützt sind. Zur Aufnah me von Kräften in Axialrichtung ist das innere Steckrohr 12 mit der Schrägscheiben aufnahme 9 in einem Bereich A verschraubt. Ein axial beweglicher Steuerkörper 14, der sich innerhalb des Zylinderblocks 2 befindet und am inneren Steckrohr 12 in axialer Richtung abgestützt ist (mittels einer Schraubverbindung B zwischen dem Steckrohr 12 und einer Halteschraube H in einem Stützkörper S), weist eine Steuerfläche E auf. Von der Fläche des Zylinderblocks 2, die der Steuerfläche E gegenüber liegt, sind Kanäle im Zylinderblock 2 zu den Zylinderbohrungen 5 geführt. Eine Zentralbohrung 15 des inneren Steckrohrs 12 ist an den Druckmittel-Versorgungskanal 10b angeschlossen, während der Druckmittel-Versorgungskanal 10a mit einem zwischen dem inneren Steckrohr 12 und dem äußeren Steckrohr 13 gebildeten Ringkanal 16 in Verbindung steht. Die Zentralbohrung 15 und der Ringkanal 16 münden im Steuerkörper 14 in Verbindungskanälen zur Steuerfläche E.Both the cylinder block 2 and the swash plate 8 are penetrated centrally by two mutually coaxial plug tubes 12 and 13 which are supported in the cylinder block 2 and the swash plate in the swash plate side recording. 9 For recording me forces in the axial direction, the inner plug tube 12 is screwed to the swash plate receptacle 9 in an area A.
